ATTACHMENT FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 561,262, dated June 2,1896.

Application filed February '7, 1896. $erial No. 578,412. (No model.)

' To 60% whom it may concern:

Be it known that I, IsAAo MARSHALL LIN- ooLN, of the city and county ofProvidence, in the State of Rhode Island, have invented a certain newand useful Improvement in Attachments for Bicycles; and Ideclare thefollowing to be a specification thereof, reference being had to theaccompanying drawings.

Like letters indicate like parts.

Figure l is a side elevation of my invention. Fig. 2 is a rear view ofthe same with the tubular supports shown in longitudinal section. Fig. 3is a view, partly in top plan and partly in section, of the lowertubular support and brace and the arms therein, as seen on line as 00 ofFig. 1;

My invention is an attachment for bicycles adapted especially forbeginners learning the use of the vehicle and for postmen and othersdesiring to leave the machine frequently standing in the street.

It consists in providing a bicycle of ordinary construction with twoside wheels mounted at the lower ends of vertical side bars, which attheir upper ends are bent and adj ustably secured in a tubular supportupon the main post, and which are braced midway by arms adjustablysecured in a tubular support or bracket, also extending from said post,as hereinafter particularly described.

In the drawings I show a bicycle of the usual or any approvedconstruction.

A designates the main post or standard of the bicycle. On the post A isthe upper tubular support a, consisting of two sleeves, integral witheach other, crossing at right angles, and each longitudinally bored, sothat said bores intersect each other at the center. The end of eachsleeve is enlarged to form there a flange, and set-screws b b c c areprovided, passing through said flanges, respectively, at one sidethereof, as shown in Fig. 2. On the post A is also a lower support orbracket d, having a sleeve or tube 6, in which there is a longitudinalbore. The ends of this tube are also enlarged, and set-screws m arethere provided, passing through said tube 2 to the bore thereof, as seenin Fig. 2.

In the bore of the tubular portion c of the bracket or support cl twoarms or bars n n are inserted, extending outwardly therefrom. They areeach provided at the outer end with an enlargement or head 0, having aslot preferably rectangular in form. Two vertical side bars or sidesupports p 19 have at their lower ends,respectively,collars or hubs qq,in which the side wheels 0 are rotatably mounted. The upper ends ofthe bars 19 p are bent, as shown in Fig. 2, and at their extremities areinserted in the horizontal bore of the tubular support a.

The bars p p are inserted in the slots at the ends 0 0 of the arms m,respectively, and in that part are preferably rectangular incrosssection, as shown in Fig. 3. By means of the set-screws b b thetubular support a is adjustable upon the postA to the desired height andfastened thereon, and by means of the set-screws s the bracket d isadjustable and secured on said post A. By the set-screws c c the bentends of the bars 13 p are fastened in a proper position in thehorizontal sleeve of the tubular portion a. By the set-screws m m thearms a n are fastened in the desired position in the bore of the tubularportion a of the bracket cl.

IVhen the rider is properly propelling the bicycle, it moves upon thewheels B D only, as usual; but if the bicycle is tipped too much oneither side the wheel 0 on that side comes in contact with the groundand supports the wheel, so as to prevent its falling sidewise. Saidsupport a and bracket d may be arranged so as to be detachable from thepost, if desired.

As seen by Fig. 2, the pedals E E are inside the planes of the bars p pand therefore are not impeded thereby.

I claim as a new and useful invention and desire to secure by LettersPatent 1. In a bicycle the combination with the post, of a sleevemovable on the post and having a tube extending at a right angle on eachside, set-screws adapted to adjustably secure said sleeve on the post,two vertical side bars having wheels at their lower ends, respectively,and their upper ends bent so as to be engageable with the tubes of saidsleeve, and set-screws adapted to adjustably fasten the bent ends ofsaid side bars in said tubes, substantially as set forth.

2. In a bicycle, the combination with the post, of a sleeve movable onsaid post, and adjustable thereon by set-screws and having a tubeextending at a right angle on each side,

two vertical side bars having wheels at their lower ends, respectively,and their upper ends bent so as to be engageable with the tubes of saidsleeve and fastened adjustably thereto by set-screws, a bracket adjustably mounted 011 said post and provided with a tubular support, andbrace-arms mounted adjustably in said tubular support at their innerends and having their outer ends engaged with the side bars,respectively, at a point on each side IO about midway upon said bars,substantially as described.
